The Shamrock Shake is back at McDonald’s to celebrate its golden anniversary.
And it’s brought along a friend.
The popular mint-flavored milkshake returns to stores nationwide today for the first time since 2017 as McDonald’s celebrates the 50th anniversary of the treat that continues to draw us back to the drive-thru window whether we’re hungry or not.
But that’s not the only news.
For a limited time, McDonald’s also is introducing a new Oreo Shamrock McFlurry.
The Oreo Shamrock McFlurry starts with the Shamrock Shake’s signature ingredients — creamy, vanilla soft serve blended with McDonald’s mint-green Shamrock flavoring and a whipped topping — and adds Oreo cookie pieces throughout.
The Shamrock Shake was created by Hal Rosen, a Connecticut McDonald’s owner and operator, in celebration of St. Patrick’s Day in 1967.
It debuted in select locations across the country in 1970 and became an instant success.
In 1974, sales from the shake helped to build the very first Ronald McDonald House in Philadelphia. The program, which keeps families with sick children together and near the care and resources they need, began when the daughter of a Philadelphia Eagles player was being treated for Leukemia.
Here are a few other things you might not know about the Shamrock Shake:
- McDonald’s introduced the Shamrock Sundae, consisting of vanilla soft serve topped with a mint-green Shamrock syrup, for a limited time in 1980.
- The “World’s Largest Shamrock Shake,” at 24 feet tall, was poured into the Chicago River in 2010. It honored a $10,000 donation to develop a new Ronald McDonald House in the city’s Streeterville neighborhood.
- The Shamrock Shake first went nationwide in 2012.
- Chocolate was added to the shake for a limited time in 2017. It was served with a straw designed by a team of aerospace and robotic engineers that delivered 50 percent chocolate and 50 percent mint in each sip.
- Participating restaurants in Philadelphia offered the Shamrock Shake on its menus twice in 2019, including the start of the NFL season in September.
- Before it became available nationwide, fans of the shake created a website to track which restaurants were carrying it.
- The Shamrock Shake will be sold in both Canada and Ireland in 2020.
